There are two versions of every coin created: the proof and the bullion. Proofs are often more detailed and have contrasting colours through the use of mirrored and matt surfaces. Bullion versions don't have the matt detailing; they were not made for collecting in design. Most of the proofs are included in sets. The £100 Britannia coin is one of these. Proofs are issued with a box and certificate of authenticity. While many of the other weights have been consistently issued in sets, this coin has also been issued as a single coin.

Weighing it at a full ounce of gold, older versions of this coin along with the newer versions have become a sought after investment coin.

After the year 2000, Britannia's sitting image was exchanged for the standing Britannia image that is still used on the coins today. The £100 Britannia coin is slightly over 32 millimeters in diameter and weighs a full troy ounce. It has a ratio of 31 grams of gold to .92 grams of alloy. 1989 and earlier coins are made from copper alloy. Coins made in 1990 and up are made with silver as the alloy.
